FLASH: Impact of frame rate on file size?

[Scott Wilkinson]

Here's a generic Flash question I've pondered (but not had time to

experiment with yet)...


How much does frame rate affect file size? Obviously (up to a point) the

higher the frame rate, the smoother the animated motion. I see many Flash

sites that--though well designed--are very "herky-jerky" on playback. I view

this a weakness of the 'net, not Flash (no bandwidth!).


I assume it's a balancing act; juggling frame rate and file size. But I

wonder if there is any kind fixed ratio (or rough approximate) at work here?

For example, if you double the frame rate from 15 to 30, does that

automatically increase your file size by X%?


There are many designers who advocate 15fps, suggesting that you don't need

more. But coming from a broadcast animation background, 15fps looks pretty

darn herky-jerky to me! (Unless used for small-scale, limited motions.)
